文摘

In this paper, “a” interfacial parameter in Nicolais–Narkis model is expressed by thickness “r_i” and strength “σ_i” of interphase between polymer and nanoparticles as well as material properties. “a” parameter is connected to “B₁” interfacial parameter in modified Pukanszky model and the effects of “r_i” and “σ_i” on “a” are explained.

The negligible difference between “a” values calculated by fitting the experimental results to Nicolais–Narkis model and also, by “B₁” results confirms the accurateness of the suggested relation between “a” and “B₁” parameters. Additionally, an inverse relation is found between “a” and “B₁” parameters for nanocomposites containing spherical nanoparticles. The results demonstrate that the slight levels of “r_i” and “σ_i” data give a large value of “a” which indicates the poor interfacial adhesion.
